Grid Navigation - Grid Navigation
|
A method of navigation developed for flying near the Earth's poles, above 70° north and south latitude. It is so named because it does not use latitude and longitude but uses a map with a grid of parallel lines. This method was devised because magnetic compasses could not be used in this region due to the large deviation of the geomagnetic field and the small horizontal component of force, but it has now been replaced by inertial navigation. → Related topics Navigation Source : Heibonsha Encyclopedia About MyPedia Information |

地球の南・北緯70°以上の両極地付近の飛行のために開発された航法。緯度・経度を使わず，平行線のグリッドを設定した地図を使うのでこう呼ばれる。この地域では地磁気の偏差が大きく，水平分力が小さいため，磁気コンパスが使用できないことから考案された航法だが，現在では慣性航法に取って代わられた。 →関連項目航法 出典 株式会社平凡社百科事典マイペディアについて 情報 |
